Detailed Implementation
[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.
[0030] Example 1
[0031] like Figure 1-10As shown, this utility model provides an integrated device for in-situ microbial detection, comprising: a base plate 1 with four casters fixed to the bottom; a power supply 2 and four first support pillars 3 fixed on the base plate 1; a middle plate 4 fixedly installed on the top of the four first support pillars 3; a magnetic frame 5 and a shaking centrifuge device 6 fixedly installed on the top of the middle plate 4; two second support pillars 7 and two third support pillars 8 arranged on the top of the middle plate 4; two fixing plates 9 arranged above the middle plate 4, the two fixing plates 9 being fixed to the two second support pillars 7 and the two third support pillars 8 respectively; a top plate 10 arranged between the two fixing plates 9; and a Nanopore third-generation sequencer 11 and a Qubit fluorescence quantitative quantitation device fixedly installed on the top plate 10. The Nanopore third-generation sequencer 12 and the notebook micro-workstation 13 are powered by a power supply 2. The notebook micro-workstation 13 includes a high-resolution touchscreen and input components, an Intel Core i9 processor, 32GB of RAM, and a 2TB solid-state drive. It supports a dual Linux system, has data storage management and analysis functions, and can run bioinformatics analysis software and handle multitasking and complex calculations. The Nanopore third-generation sequencer 11 measures 160mm*115mm*30mm and consists of an OLED touchscreen and a SpotOn sequencing chip. The SpotOn sequencing chip has SpotOn sample wells for adding pre-processed sequencing libraries, allowing direct processing of raw DNA or RNA. Sequencing capabilities include read lengths from 200 bp to 2 Mb, with real-time data acquisition and rapid result generation. Its single-molecule real-time sequencing technology can be used in various research fields such as whole-genome sequencing, RNA sequencing, and metagenomic sequencing. The Qubit fluorescence quantitative quantitation instrument 12 measures 135 mm * 25 mm * 5.5 mm and consists of a touchscreen display and optical detection components. It supports sample volumes of 1-20 μL to meet diverse experimental requirements, with each sample processing time less than 5 seconds, significantly improving experimental efficiency and meeting the needs of in-situ measurements outside the laboratory. The magnetic rack 5 consists of a magnet assembly and a support. The magnet assembly is composed of high-performance neodymium iron boron magnets, capable of generating a strong magnetic field for adsorbing and processing samples. The device utilizes magnetic microbeads, whose powerful magnetic field ensures efficient adsorption of magnetic materials, reducing sample loss and improving experimental efficiency. The support is compatible with 1.5-2ml centrifuge tubes, used to fix the magnet assembly and place the centrifuge tubes; each side can hold 10 centrifuge tubes, with a maximum of 20 tubes at a time. This device integrates a power supply (2), magnetic support (5), shaking centrifuge device (6), Nanopore third-generation sequencer (11), Qubit fluorescence quantitative quantitation system (12), and a laptop workstation (13), allowing for convenient outdoor transport for real-time monitoring and continuous detection. This avoids potential changes in microbial activity, quantity, and community structure during transportation and laboratory processing, thus preventing discrepancies between test results and actual conditions.
[0032] Example 2
[0033] like Figure 1-3 As shown, the integrated device for in-situ detection of microorganisms also includes a protective cover 14, which is fixed to the first support column 3 and the top plate 10 by multiple screws. The protective cover 14 protects the power supply 2, the magnetic rack 5, the shaking centrifuge device 6, the Nanopore third-generation sequencer 11, the Qubit fluorescence quantitative instrument 12, and the laptop micro workstation 13.
[0034] Furthermore, a spiral groove 15 is provided on the base plate 1. The spiral groove 15 is used to limit the position of the protective cover 14. When the protective cover 14 is installed, the protective cover 14 is first inserted into the spiral groove 15, and then the protective cover 14 is fixed with screws.
[0035] Furthermore, two rotating shafts are fixed on both sides of the top plate 10, and the two rotating shafts are respectively rotatably connected to the corresponding fixed plates 9. When the entire device is under the protection of the protective cover 14 (e.g., Figure 4 As shown), the equipment on the top plate 10 is positioned downwards. However, during testing, the top plate 10 needs to be rotated 180° to flip the downward-facing equipment upwards (as shown). Figure 6 (As shown), so that personnel can conduct water sample testing.
[0036] Furthermore, a connecting plate 16 is rotatably mounted on one side of the fixing plate 9. The connecting plate 16 is fixed to the top plate 10 by screws. The connecting plate 16, in conjunction with the screws, ensures that the top plate 10 is in a fixed state.
[0037] Example 3
[0038] like Figure 8-10 As shown, two fixed rectangular rods 17 are fixedly installed at the bottom of the two second pillars 7, and two movable rectangular rods 20 are provided on the two third pillars 8. Two rectangular holes 18 are opened on the base plate 1, which are adapted to the fixed rectangular rods 17. Four rectangular slots 19 are opened at the top of the intermediate plate 4, and both the fixed rectangular rods 17 and the movable rectangular rods 20 are adapted to the rectangular slots 19. The design of the rectangular holes 18 and rectangular slots 19 allows the device to achieve two forms of conversion. When the two fixed rectangular rods 17 and the two movable rectangular rods 20 are respectively located in the corresponding rectangular slots 19, the entire device is in a highly superimposed state (e.g., ...). Figure 6 As shown), this state facilitates transportation; when the fixed rectangular rod 17 is located in the two rectangular holes 18, the entire device is in a flat state (as shown). Figure 9 As shown in the figure, this state is convenient for personnel to operate, and users can switch the state of the device according to the specific usage environment.
[0039] Furthermore, a sliding groove 21 is provided at the bottom of the third support column 8, and the movable rectangular rod 20 is slidably installed inside the sliding groove 21. Limiting grooves 22 are provided on the sides of the two third support columns 8 that are close to each other. The sliding groove 21 and the limiting groove 22 are connected. A lead screw 23 is fixedly installed on one side of the movable rectangular rod 20. The lead screw 23 passes through the limiting groove 22, and a nut 24 is threaded on the outside of the limiting groove 22. Through the above design, the position of the movable rectangular rod 20 can be adjusted, so that the height of the third support column 8 and the movable rectangular rod 20 can adapt to the height of the device after it is laid flat. In specific adjustment, first loosen the nut 24, then adjust the movable rectangular rod 20 to a suitable height, and finally tighten the nut 24.
